A lack sleep makes me sick
Few things make me sicker or miserable faster than a lack of sleep.
To be productive I find I need at least nine hours of sleep a day and anything less than eight makes me downright miserable, giving me headaches and making me feel congested and generally miserable.
This day in age there much that can keep one up late – downloaded YouTube videos to watch, things to scroll in your social media posts, heck even things I can work on in my blog. But if I want to be happy, I must resist and go to bed early.
